Throughout the several views in the drawing forming a part of this specification like numerals designate like parts.

Referring to the drawing in detail, the numeral 'I designates a tubular member of suitable shape in which the material to be dispensed is placed. A retainer 8 is formed with a suitable opening S. The retainer 8 is preferably detachably secured, forced-on or cemented to one end of the tubular member 1. A screw threaded part I0 has preferably a reduced and tapered end toprovide a joining portion I I. The joining portion II carries a spring washer I2 and is rotatably mounted in the retainer 8. The spring washer I2 is intended to take up back slack and to retain a slight friction. A knurled handle another pre- `part I3 is formed with an opening III, and holes 5 5 I5 and I6, Fig. 11. The opening I4 in the knurled handle part I3 engages the joining portion II of the screw threaded part I0. The knurled part of the handle is detachably secured to the joining portion II of the screw threaded part IU by a snap-on or forced-on fastening member I'I.

The holes I5 and I G are suitably arranged in the handle of a mountable type of my device, when the handle part I3 serves as a base, likewise as shown in Fig. 11, so that the device can be conveniently mounted on to a work bench, wall, cabinet door, or other suitable place.

A one-piece piston I8 is preferably formed with a circumferential or part-circumferential groove I9. The one-piece piston I8 permits slidable movement in the tubular member 1, the leading edge and side of said one-piece piston makes a good t with the inner surface of the tubular member.

A connecting piece or sleeve is preferably formed of a single strand of `wire suitably coiled and engages and cooperates with the screw threaded part Ill. An eye 2! is formed at one end, being suitably shaped to snap into the groove I9 so that the one-piece piston I8 may be quickly and securely attached to the connecting piece 20. A spring arm or loop 22 at the other end provides means to prevent rotation of the connecting piece and may be of any approved shape. The spring arm or loop 22 is tensioned against the inner wall of the tubular member and provides an anchor like grip but permits sliding movement longitudinally of the tubular member when pressure is applied. In order to make a standard rigid structure of the coiled type of the connecting piece, the coiled portion may be prepared for a solder bath. During the course of soldering care should be taken so as not to interfere with the normal condition of the eye 2| and the spring arm or loop 22.

A massage brush or applicator 23 is formed with a circumferential groove 2f. The massage brush or applicator 23 is preferably produced of resilient materials, such as rubber, fabric, etc., and has an axially disposed iiap valve like dispensing outlet 25. The outer portion of the massage brush is formed with a plurality of teeth 25 which may be of suitable shape and stiffness. Preferred shapes of teeth oi interchangeable massage brushes are shown in the drawing. A fitting 2'! is formed with an aperture 23 and detachably engages the groove it of the massage brush 23. rllhe fitting 2i is threaded to the opposite end of the tubular member from the retainer 8. The massage brush is firmly held in place and its dispensing outlet 25 communicates with the interior of the tubular member. A suitable liner 29 protects the massage brush against discoloration. The liner 2Q has an opening 3G which communicates with the dispensing outlet 25. The tubular member may be sealed by a suitable full iace liner 3l, sho-wn in Figs. 5, 9, 10.

An externally threaded connecting ring 32, shown in Figs. 8, il, serves as a convenient connecting means in order the tubular member is to 'ce produced of unthreadable materials, such as bakelized paper, fibre, plastics, ete. The con.- necting ring 32 may be forced on` or cemented on to both ends of the tube.

The rear end portion of the massage brush or applicator' is enclosed and coniined in the fitting, and the enlarged outer free end portion is protected against accumulation of germs, particles of dirt or foreign matter by a cover or cap 33 positioned upon the prepared peripheral portion of the fitting 2l when the device is not in use.

An interchangeable dispensing cap member 34 is formed with discharge openings 35 Which is intended for special dispensing purposes. The discharge openings 35 may be closed by the full face liner 3I so that the dispensing cap member 34 may be utilized as aclosure. An interchangeable closure 36 may be employed when material is to be kept in the device for any considerable period of time.

These attachments increase utility of the dispensing device. The component parts may be readily disassembled and easily reassembled.

The lling of the tubular member l is accomplished on the removal of the iitting 2 which carries the massage brush or applicator 23 and the liner 29. After the one-piece piston I8 is brought to desired position, then the tubular member may be filled with facial cream, powder,

tc. In this instance the dispensing device may be successfully operated after the tting 27, the massage brush or applicator 23 and the liner 29 are replaced.

En operation, the tubular member l and the handle i3 are relatively rotated in contrary direction, this causes the one-piece piston i8 to move ionvard. Thus, a desired quantity of facial cream is forced through the outlet 25 onto the outer portion of the massage brush or applicator 23 ready for application.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size,

yforced on to one end of said tubular member, said retainer being formed with a suitable opening, a

screw threaded shalt `being formed with a joining f' portion and rotatably mounted in said retainer, a

spring washer positioned upon said joining portion so as to retain a slight friction, a knurled handle being removably united with said joining portion of said screw threaded shaft by a snap-on i or forced-on fastening member, a one-piece plston being formed with a circumferential groove the piston being tted and movable in said tubular member, a conifzecting piece having a resilient eye clamped to said one-piece piston, said connecting piece spirally engaging said scre'er threaded shaft, a suitably shaped spring' arm or loop being formed at the other end ci said connecting 4piece aiording a means to hold said connecting piece against rotation when said handle is rotated to move said connecting piece and said one-piece piston in said tubular member.

2. A dispensing device comprising a tubular member, a retainer being detachably secured to one end of said tubular member, said retainer lbeingr formed with a suitable opening, a screw threaded shaft being formed with a joining portion and rotatably mounted in said retainer, a
